The invention herein disclosed relates to the manufacture of rafiia covered bowls.

These are produced usually by adhering the end of a strip of rafiia to the bottom of the bowl and then winding the strip spirally from that point across the bottom and then over the sides of the bowl.

Difficulty is frequently experienced in attaching the rafiia and getting the coil started on the bottom of the bowl.

Objects of the present invention are to provide means for starting the coil separate from the bowl and which can then be used to apply and secure the coiled strip to the bottom of the bowl.

It is a further purpose of the invention to provide such means in a simple, practical and inexpensive form which can be easily used without any previous experience or training.

Other desirable objects attained by the invention are set forth or will appear in the course of the following specification.

The drawing accompanying and forming part of the specification illustrates an embodiment of the invention and the new mode of operation which it makes possible. Structure, however, may be modified and changed as regards this illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

Fig. 1 in the drawing is a perspective view of the disc for starting the coiling action;

Fig. 2 is a similar view showing the end of a strip of raffia inserted through a holding opening in the disc and the first turn taken about the post at the center of the disc;

Fig. 3 is a plan view showing how successive coils are wound over the face of the disc;

Fig. 4 is a cross sectional view of the disc as on substantially the plane of line 44 of Fig. 1;

Fig. 5 is a bottom plan view of a bowl with the disc on which a layer of the raflia has been coiled, applied;

Fig. 6 is a side elevation of the bowl with the disc left in place and the strip wound up over the sides of the bowl;

Fig. '7 is a perspective view of the completed bowl.

In this invention a layer of raffia is first coiled on a disc I!) and then this layer is secured as a unit to the adhesively coated bottom of the bowl H. I

In starting, the end of the rafiia is temporarily secured near the center of the disc by inserting 2 Claims. (Cl. 1541.7)

2 it through a hole [2 of a size to snugly receive the end of the raffia strip i3.

Adjoining the retaining hole and located substantially at the center of the disc, is a small pin or post M of about the same diameter as the raffia and projecting from the face of the disc a distance approximately the same or less than the diameter of the rafiia.

Figs. 2 and 3 show how with the end of the raifia caught in the opening it, successive coils may be wound over the face of the disc, this being easily accomplished by relatively rotating the disc while holding the raffia under light tension and pressed flat against the face of the disc.

After a layer of coiled rafiia is completed as in Fig. 3, the entire layer may be applied as a unit to the bottom of the bowl, after this surface of the bowl has been coated with suitable adhesive, by simply reversing the disc and pressing the layer firmly over the coated surface, as in Fig. 5.

After allowing suificient time for the adhesive to set, the disc may be removed by simply lifting it away from the adhesively attached coiled layer.

In removing the disc care should be observed to prevent the disc from pulling the end of the raffia in the hole [2 away from the attached layer. This can be assured by pressing inward on the end exposed in the hole [2 as the disc is lifted away from the attached layer, using a pick to force the end back out of the hole.

Fig. 6 shows how the winding may be continued across the bottom and up the sides of the bowl while the disc remains in place, held to some extent by the end of the raffia engaged in the retaining hole. This is not necessary however, as the disc may be removed as soon as the layer coiled thereon has become firmly attached to the bowl.

The winding or starting disc may be made of plastic or other such material, molded all in one piece, substantially as indicated in Fig. 4.

The device is simple, practical and inexpensive and provides a means by which anyone may quickly and easily form a preliminary coiled layer of raiiia and then attach it to the bowl or other structure and which can then be removed, leaving the coiled layer firmly secured in place and providing the beginning of the complete rama covermg.

The center winding post [4 may be of substantially the same size as the rafiia but ordinarilyshould not project from the face of the disc be yond the diameter of the rafia, so as not to pre- 3 vent the rafiia from being pressed firmly against the bottom of the bowl.

What is claimed is:

1. A device for forming and applying a coiled layer of raffia to the bottom of a bowl, comprising a flat disc having an opening near the center of the same, of a size to receive the end of a strip of raffia, and a post of about the same diameter as the raflia, adjoining said opening and located substantially at the center of the disc and projecting from the face of the disc a distance approximating the diameter of the raflia and about which a length of raffia, caught at the end in the opening, may be wound in an ever increasing spiral in a single fiat layer on the face of the disc and which may be applied by the disc in a single layer over the bottom of the bowl.

2. The method herein disclosed of applying a starting layer of coiled raiiia to the bottom of a bowl which has been coated with adhesive, and comprising providing a disc with a hole near the center and a projecting post adjoining the hole and substantially at the center of the disc, inserting the end of a strip of rafiia through said hole and then winding the strip about said post in an ever increasing spiral layer over the face of the disc and then applying the complete layer to the adhesively coated bottom surface of the bowl by pressing the layer covered face of the disc against the adhesively coated bottom of the bowl and thereafter lifting the disc away from the applied layer and in so doing freeing the hole in the disc from the end of the raffia.
